A letter to the editor is presented on the spectroscopic evaluation of native, milled, and functionalized Î²-TCP seeding into dental enamel lesions, by Robert L. Karlinsey et al in the (2009) 44 issue.

A response by Andrew P. Sage, Yin Tintut, and Linda L. Demer to a letter to the editor about their article regarding the formation of calcium phosphate nanocrystal independently of cells under hyperphosphatemic conditions in vitro is presented.

Calcium phosphate bone cements (CPBCs) are osteotransductive, i.e. after implantation in bone they are transformed into new bone tissue. Furthermore, due to the fact that they are mouldable, their osteointegration is immediate. Their chemistry has been established previously. Some CPBCs contain...

The growth of known biologically-relevant mineral phases on semiconducting surfaces is one strategy to explicitly induce bioactivity in such materials, either for sensing or drug delivery applications. In this work, we describe the use of a spark ablation process to fabricate deliberate patterns...
